For evaluating the hepatic function, intrinsic substances are influenced by the physiological activity of homeostasis. Potential reduction of the hepatic reserve can be evaluated by the loading of the extrinsic substances. Asialoglycoprotein (ASGP) receptor reduces its activity according to the grade of hepatic parenchymal injury. The quantitative evaluation was possible with 99mTc-galactosyl H...

A 28-year-old woman with a deformed thorax and kyphoscoliosis associated with Klippel-Feil syndrome developed respiratory failure with pulmonary hypertension. Pulmonary 133Xe ventilation and 99mTc-MAA perfusion scintigraphies showed maldistributions of lung ventilation and perfusion, and noticeably delayed 133Xe washout from the lungs. Dynamic breathing MR imaging showed poor and/or asynchronou...

OBJECTIVE To assess lung perfusion patterns in inpatients with acute viral bronchiolitis using quantitative 99mTc-MAA scintigraphy so as to establish an association with clinical and radiological findings. METHODS A comparative, prospective case series study with a focus on diagnosis was carried out in a population of patients with acute viral bronchiolitis admitted to Hospital de Clínicas de...
